E l 3 Claims.

This invention is for improvements in or relating to hinges for windows, fanlights and the like opening outwardly.

It is frequently a difficulty with casement winllL dows with sashes and fanlights opening outwardly, that whilst the inside of the window or fanlight can r'readily be `cleaned from the inside of the building, it is very awkward indeed and in many cases quite impossible to clean the outside there- 1i?. from. Y

i vThe object of the present invention is to provide a simple solution to this diculty, which will enable the outside of windows, fanlights and the like opening outwardly to be as readily cleaned as the inside from the inside of the building and with perfect safety. l According to the invention, a hinge for a hinged window,` fanlight or the like arranged to open outwardly comprises a longitudinally slotted plate 20 which is arranged tobe afxed to the frame of the l window or thelike along a member thereof extending transversely to the axis of hinging `of the window sash, fanlight `or the like; a second plate which is arranged to be affixed to the win- 25 dow sash or the like along a member thereof which when thewindow sash or the like is in closed position overlies the said member of the frame, the second plate thus overlying the rstplate face to `face therewith when the window sash 3W or rthe like is in closed position, and which second plate is pivotaloly` and slidably connected to the rst plate by a pin engaging in the slot therein and slidable therealong as the window sash or the like is opened and closed; and a link pivotally g connected at one end to-the first plate at a ypoint near the end thereof whereat `the `pin of the slidingconnection of the two plates is positioned when the window sash or the like is in closed position, and at the other end to the second i plate at` the end thereof remote from' the end at lwhich the said pin is positioned. p

As willbe understood, `a window sash, fanlight or the like is hung upon a pair of such hinges, one atthe top and one at thebottom in the case of4 a fcasement window sash, or one ateach end inthe case of a fanlight. ',:With the improved `hinge of this invention, it is lreadily possible to clean the outside of an outwardly `opening window sash, fanlight or the like 50 from the inside of the building, as when the win dow, fanlight or the likeiis open, a space is provided=between the frame and the edge of the window sash or the like, at `the hinged side thereof,` sufficient to enable the cleaner to insert'his 5m hand and'if necessaryhis arm, to gainaccess to (ci. ifs- 166) the Outside of the sash or the like. This is due; as will be appreciated, to the fact that as the window sash or the like is pushed open, the pin hereinbefore referred to its caused, by the action of the parts, to slide along the slot in thefirst 5 member and carry with it the whole of the window sash or the like bodily away from the frame as Well-as rotating the same through say 90.

The invention will now be further described with reference to the accompany drawing, which illustrates a preferred embodiment by way of example, and in which,

Figure l is a side elevation of the hinge;

Figure 2 is a plan view with the parts of the hinge in closed position; t

Figure 3 is a plan view with the parts of the hinge in open position; and

Figure 45 is a front View of a easement window ntted with the improved hinges of the invention.

Like reference numerals indicate like `parts in the various figures.

Referring to Figures l to 3, the hinge comprises a slotted plate 1. This plate is arranged tobe affixed to the frame of the window along a member thereof which extends transversely to the axis of hinging of the Window sash. This member is the bottom member 2 ,of theIwindow` frame or the top member 3 thereof in the case of the lower and upper hinges respectively of the lower lefthand window of the easement Window shown in Figure 4. The hingefurther comprises a second plate 4 which is arranged to be affixed to `the window sash along a member thereof which when the `sash is in closed position overlies the said member (2 or 3) lof the window frame. This 35 member is the bottom member 5 or the top member E of the window sash in the case of the lower andupper hinges Irespectively of the said lower left-hand window of the easement window of Figure 4. l n l As will be seen from Figures 1 and 2, the second plate 4 overlies the vrst plate l face to face therewith when the window sash isin closedvposition and correspondingly the parts of the `hinge are in closed position. t

The second plate: 4 is pivotally and slidably connected to the first plate I by a pin 'l engaging in a slot inthe plate I and slidable therealong as the" window sash is opened and closed.

The hinge further comprises a link 9 pivotally connected by a pin Il) to the plate l and by a Second pin ll to the plate 4, the pin IIJ being situated as shown, at a point near the end of the plate l whereat the pin l is positioned when the window sash is in closed position and the pin II being situated at the end of the plate i4 which is remote from the end at which the pin 'I is positioned.

'Ihe plate I is provided with a number of holes I2 for the reception of screws or the like for fastening the plate to the member 2 or 3 of the window frame to which it is to be affixed :and the plate 4 is similarly provided with holes I3 for the reception of screws or the like for fastening it to the member 5 or 6 of the window sash.

The link 9 at the end where it its connected by the pin I0 to the plate I is bent, as shown, substantially into the plane of the plate 4. In this way, easy fixing is provided for an easy movement in the case of windows with projecting transoms and sills. Alternatively, the link can be straight and a washer be inserted between it and the plate I, around the shank of the pin I0.

For clearance and easy movement, moveover, there may be a washer between the plate I and the plate 4, around the shank of the pin I, the eiect of this washer being to space the plates I and 4 a short distance of clearance from one another as the parts of the hinge move in the opening and closing movements thereof.

In Figures 2 and 3, the window sash is shown in chain line at I4 and in Figure 3, the window frame is shown, also in chain line, at I5. It

l will be seen. from a perusal of the Figures 2 and 3 that when the window is in closed position and the parts of the hinge are correspondingly in closed position, one edge of the window sash, namely the edge marked I6, is adjacent the end of the plate I of the hinge at which the pin'l is situated, while when the window is in open position and the parts of the hinge are correspondingly in open position, the said edge I6 of the window sash is removed along the direction of the length of the plate I to a position adjacent the opposite end of that plate from the end at which the said pin is situated. The result is, as hereinbefore described, that a persons hand and arm can be inserted between the opened window and the edge I1 of the window frame (see Figure 3) corresponding to the edge I6 of the window sash.

. Figure 3 also shows in chain line at I8 the movable parts 4, 9 of the hinge inthe relative positions they occupy in the course of their opening movement to the fully open positions in which they appear in full line in Figure 3.

. As will be seen, the casement window shown in Figure 4 comprises four separate windows I9, 2B, ZI, 22, two of which, namely the upper two, hinge about horizontal axes and the other two about vertical axes. In the case, therefore, of the two lower windows, the plates I of the hinges are aflixed to the horizontal members 2, 3 of the window frame, while in the case of the two upper windows, the said plates I are ailixed to the side members of the window frame.

It will be understood, of course, that the improved form of hinge according to the present invention can be applied either to wood-framed windows, fanlights and the like, or to those which are constructed with metal frames, the general principle of operation and construction of the hinge being the same in both cases.

What I claim as my invention and desire to secure by Letters Patent of the United States is:
